Jp. Hirth, LEDGES AND DISLOCATIONS IN PHASE-TRANSFORMATIONS, Metallurgical and materials transactions. A, Physical metallurgy andmaterials science, 25(9), 1994, pp. 1885-1894
The coupling of dislocations and ledges in phase transformations is co
nsidered in terms of the symmetry of phases meeting at an interface. G
rowth and structural ledges and a variety of dislocation arrays are tr
eated. Symmetry and the absence of long-range strain fields alone are
shown to produce few restrictions on possible interface structures.
